Hello,
Oops, looks like an oversight in our part.
You can figure out what the options are by looking at the user interface elements for those inputs in SAM -- for the PVWatts model, at the bottom of the System Design page.
I updated the source code at
github.com/NREL/ssc/blob/develop/ssc/cmod_battwatts.cpp so the variable descriptions will be more meaningful in the next version of SSC.
For
:
0 = lead acid
1 = lithium ion
The variable metadata suggests that 2 is a valid value, but it does not appear as an option in the user interface or the source code.
For
:
0 = peak shaving look ahead
1 = peak shaving look behind
Best regards,
Paul.
